Methodology: How We Ranked the Best Solar Companies in Berkeley

EcoWatch's solar experts analyzed each solar company in Berkeley based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Berkeley


Below are some the criteria we examined specifically for Missouri solar companies

  • Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
  • Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
  • Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
  • Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
  • Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
  • Availability (10%): The bigger the service area, the higher the company will score.
  • Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
  • Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.

The Cost and Benefits of Solar in Berkeley

Solar panels run off a free energy source — the sun — but to take advantage of this you will first need to pay to install your panels.The cost of solar and the savings it generates vary depending on some key factors such as:

  • Typical energy usage: The more electricity your home uses on average and the greater your current power bills are, the more likely you'll benefit from switching to solar.
  • The amount of sunlight your city gets: Due to Berkeley’s high amount of average daily sunlight, you should be able to save a decent amount on your power bills.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $16,000 over the first 20 years with your solar panels, too.
  • Choice of solar panels: The type of solar panels you want will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.

Although a solar panel system costs a decent chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on several factors, such as the size of your house and your energy consumption.

Solar Incentives in Berkeley

One of the benefits of installing a solar panel system is receiving government incentives.On top of the federal solar investment tax credit, there are also some local benefits, which in most cases, can be claimed in addition to the federal incentive, so you get to save even more. You can find out about the incentives available to you in our article on solar incentives

Environmental Impact of Switching to Solar in Berkeley

Swapping traditional energy for solar is a powerful way to do what you can for a cleaner and more sustainable future.But you may be wondering – how much exactly can you help by making the switch to solar? The amount of energy you use is an important factor to think about. The more electricity you use, the larger your impact when you make the switch to solar power.Because solar panels don’t release greenhouse gas emissions into the atmosphere when generating electricity, they’re a good swap for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 100 pounds each year. If you want to do what you can for the environment, you’ll no doubt understand that there are many advantages to adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is invaluable.

EcoWatch's Berkeley, MO Solar Company Rankings FAQs

What is the best solar company in Berkeley?

In Berkeley, Astrawatt Solar is the best local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're planning on installing solar panels on your house.

Are solar panels really eco-friendly?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth putting solar panels on my house?

Solar panels need a considerable upfront investment that will cost you several thousands of dollars, but whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

How often do solar panels have to be replaced?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
